The second connecting arm 13 can be driven to move through the expansion and contraction of the expansion and contraction oil cylinder 14, and accordingly the first connecting rod 10 is driven to rotate around the first hinge point 15, so that the deformation of the four-bar mechanism is realized. Of course, in other embodiments, the four-bar linkage may be actuated to deform by other arrangements, such as by a movable member pushing the four-bar linkage to deform.

In a state where the first connecting arm 12 and the second connecting arm 13 extend horizontally, an included angle between the telescopic cylinder 14 and the vertical direction is greater than 0 degrees and less than or equal to 5 degrees. When the telescopic cylinder 14 is perpendicular to the first connecting arm 12 and the second connecting arm 13, the telescopic movement of the telescopic cylinder will not cause the first connecting arm 12 and the second connecting arm 13 to move, so the telescopic cylinder 14 is not perpendicular to the first connecting arm 12 and the second connecting arm 13, and the telescopic cylinder 14 is prevented from being blocked.
